Air velocity transducer KGF15
Overview
Used for wind speed detection of underground main wind tunnel and Wind gap the main fan and Shaft mouth,ensure the safe produce of coal mine, the Air velocity transducer KGF15 is intrinsic safety ,is one kind Intelligent test instrument ,convenient to use and can suit with alll kinds of Coal mine safety monitoring system ,this sensor realize the fully digital design,wind speed probe select Stability good ultrasonic components ,the ultrasonic putout frequency signal corresponding to the wind after Wind speed modulation demodulation and waveform shaping circuit processing,and sent to handled by single-chip microcomputer circuit, then putout corresponding frequency signal and display the speed value locally.
The program memory /data-carrier store/microprocessor /input and output contact Integrated by singlechip,Performance is good,high reliability .
Main technical parameters:
Explosion-proof form Mine intrinsically safe “ExibI”
